[An intraosseous hemangioma in the perpendicular lamina of the ethmoid bone]

The incidence of intraosseous hemangiomas is very low. Most of them occur in adult females. The mandible,the zygoma,the maxilla, and the frontal and nasal bones are the areas of most frequent localization in the facial region. The intraosseous hemangioma is a benign, slowly growing,bony hard tumor causing facial deformity. It is diagnosed histologically. We report a case of an 18-year-old male with an intraosseous cavernous hemangioma located in the perpendicular lamina of the ethmoid bone. Intraosseous hemangioma often has characteristic signs on a CT scan, with either coarsened trabeculae lying adjacent to the vascular channels or multifocal lytic areas creating a honeycomb pattern. Because of the age of the patient we considered a midline granuloma and a chondrosarcoma. The therapy of choice is surgical excision; radiation is done in exceptional cases only.
